ENHANCED NETWORK MONITOR SYSTEM FOR AUTOMATED BANKING MACHINES

摘要

An enhanced network monitor system (30) processes event messages and command response messages from automated banking machines such as ATM terminals (36). Both message types are assigned a single transactio n code. The system includes an application program (34) in which the event messages and command response messages are processed in a host computer by parallel message processing regions (52, 54, 56). A modified VTAM communications protocol enables the application to control sequencing of messages generated by the ATM terminals. This enables both event messages and command response messages to be run in a response mode. The transaction processing limit for the parallel message processing regions may be set to a maximum value. The parallel message processing regions run the single transaction repeatedly without reloading which increases the rate at which messages are handled.
